BACKGROUND--FIELD OF INVENTION Bristle bundles forming a brush head on the tip of a toothbrush head-sector, with an 15 orifice within, which links to an accordion dentifrice cartridge by an underlying tube.

Several additional versions have been designed. One is a switchable, disposable brushhead plate that serves as an opening and closing mechanism of conveyance of S"dentifrice from an accordion cartridge. Another version is of a non-switchable, disposable brush-head plate. Yet another version of a comb-brush is implemented as alternative embodiment.

BACKGROUND-DESCRIPTOPN OF RELATED ART It is apparent that a majority of population lacks oral care awareness, which subsequently aggravated to a variety of serious oral ailments. To a large extend, the shortcoming can be improved primarily by having a tooth brushing after each meal. It is ooeo understandable that somehow, not convenient to carry the bulky household toothbrush oooo and a clumsy tube of toothpaste in one's hand bag or sachet, not to mention stacking one in one's pocket. Although there had been suggestion of prior art which claimed to have built several types of toothbrush trying to meet such a need. So far none had been able to offer the kind of features that this invention offers.

This invention relates to a brush head on the tip of a toothbrush head-sector with an orifice surrounded by bristle implants, which links to an accordion cartridge by an underlying tube. Several alternative versions have been designed. One is a switchable, disposable brush-head plate that serves as an opening and closing mechanism, thus controlling a thoroughfare of conveyance of dentifrice from an accordion cartridge.

Another version is of a non-switchable, disposable brush-head plate, and yet still another version of a comb-brush all of which can be disposed of or replaced by screwing on and off at the mid-joint or female screw-joint in different versions. All versions set forth in this invention enable the user to carry the brush on all occasions for spontaneous use.

The use of toothbrush of the type, which intended to dispense toothpaste from an attached container onto the bristles had been suggested in prior art shown in U.S. Pat.

Nos. 4,615,635; 5,832,940; 5,860,522. French Pat. 2,629,322. German Auslegeschrift No. 2,639062; 29,719,257.4; 29,815,277.0.

The German invention DE 2,639,062 did not show as to how the dentifrice is introduced •to the bristles from the cylinder and how refill could be fulfilled. Without a clear indication as to how it could be activated, rendered the invention unserviceable.

0 000: *20 The French invention 2,629,322 also failed to demonstrate as to how the dentifrice is to be transfused onto the bristles and how refill could be replenished, rendering this invention a mere conjecture.

The other German invention DE 29,719,257.4 provided only a sketch of the general 0 25 outlook of his concept with no reveal of its novel functionality.

Yet German invention DE 29,815,227.0 is another conjecture which lacks detail description of his invention.

U.S. Pat. No. 4,615,635 to K. H. Kim (1986). The shape of the brush-head was designed with the middle part jutting out. This protruding part on the brush would scratch on the teeth during brushing. The brush-head comprises of two parts, rendering 3 replacement more cumbersome. Moreover, special size toothpaste tube has to be manufactured to accommodate this invention. Without the availability of a right size toothpaste tube, the invention would become unserviceable.

U.S. Pat. No. 5,832,940 to Darryl Embry et al (1998). The invention of collapsible cover did not offer any particular advantage to the users. There is no mention as to how the dentifrice is conveyed to the bristles. It failed to deliver to the users the service it claimed to offer in the first instance.

U.S. Pat. No. 5,860,522 to Jae Ho Lee (1999). The invention claimed to be a toothbrush case. Such an invention could not have superceded the idea of simply packing a toothbrush and toothpaste tube in one's travelling kit. This invention also could not curtail the cumbersome of which the inventor purported to overcome when he conceived the design.

SUMMARY

Fig. 12B shows that a push forward motion at the bottom of brush-head plate 20 will force the brush-head orifice 26 to be engaged with receptor orifice 32 underneath to be vertically in position with one another. The vertical alignment will open the thoroughfare of dentifrice to be transfused from the accordion cartridge 38, onto the bristle cradle 24, via the underlying tube 28. When the 2 orifices 26 and 32 are vertically connected, clickmarks 58 and 59 on the plate 20 will grip with a pair of front click-marks 52 and 53 inside the troughs, locking the brush-head plate 20 firmly on the receptor Fig. 12C shows that a push on the tip of the brush-head plate 20 inward will disengage the 2 orifices 26 and 32 to be drifted apart, thus closing the thoroughfare of conveyance of dentifrice. When this happens, a pair of click-marks 58 and 59 on the brush-head plate 20 will grip with the rear pair of click-marks 54 and 55 in the trough on the receptor locking the plate's movement. The open and blocking mechanism will also .safeguard spill of unwanted toothpaste and keep the dentifrice fresh and uncontaminated. The extend of slidability of plate 20, are governed by the catch-rifts, ••troughs and the click-marks built therein.

13A-13D, Fig. 14, Fig. 15 Fig 16. Additional Embodiment I I.

Fig. 13A is a receptor 30A, which is a similar design of 30 but without the click-marks 52, 53, 54 and 55 in the troughs. It is a receptor for a non-switchable disposable brush-head plate 20A with a male screw joint 48A that can be screwed onto the female screw joint 42A of a chamber-handle 84, which contains a cavity into where toothpaste is stored.

Dentifrice can be conveyed onto the bristle bundle 22A by simply compressing on the chamber-wall 86. Refill can be conducted with an elongated adapter 92 through the tail refill inlet 82.

12 Fig. 13B shows a non-switchable disposable brush-head plate. It is non-switchable because the distance between the front 60A and rear 61A catch-rifts are the same in length to that of the receptor 30A, fitting into one another neatly upon mounting.

Fig. 13C is a handle that is designed without accordion cartridge. The top and bottom parts of the chamber are molded with heavier plastic material forming a handle, while the walls of the handle are molded with thinner soft plastics. Conveyance of dentifrice can be affected by compressing on the supple chamber wall 86.

Fig. 13D shows that refill of chamber storage 84, can be conducted by poking the elongated adapter 92 deep into the chamber via the tail refill inlet 82 by attaching a household toothpaste tube Figs. 13E, 13F, 13G, 14 16. Alternative Embodiment.

•Advantages From the description above, a number of advantages of this invention become evident: Bristle implants on the tip of a brush head-sector with an orifice, which links to an accordion dentifrice cartridge by an underlying tube.

The design of replaceable, disposable brush-head is economical and environmental friendly.

13 The size of the toothbrush is made within the confine of portability. To achieve that, it is designed to a size similar to that of a marker pen, so it can be carried around, put into pocket or sachet, providing an all-time oral cleansing facility away from home.

The adoption of the accordion dentifrice cartridge ensures easy transfusion of dentifrice to the brush-head. The accordion design makes it easy to squeeze. Refill can be fulfilled easily. The content in cartridge is about 8g. As only a dab of dentifrice is needed for each tooth brushing, the content will be enough for about 14 applications after each refill. New cartridge can also be replaced if so desired.

A twin adapter of large and small screw-size is designed to facilitate refill from a domestic tube by simply screwing one of the two onto the mid-joint. Supply of domestic toothpaste is readily available in the market. Refill of non-switchable version is via the tail refill inlet with an elongated adapter.

The switchable version of the brush-head plate serves many advantages. It is easy to mount onto the receptor. Control of flow of dentifrice is easy. It can also be replaced when worn out.

The orifice-lock built inside the cap in non-switchable version is a design that safeguards the unintended spill of dentifrice. Moreover, it keeps the toothpaste fresh and free from contamination.

20 Various handle designs facilitate manufacturing specifications.
